Detailed description of the invention
With reference to Fig. 1, Fig. 2, a kind of double; two light source led lamps that the present invention proposes, including: supply module, the first light source 1, secondary light source 2, switching circuit, base the 3, first diffuser 4 and the second diffuser 5.
First light source 1 and secondary light source 2 are respectively mounted on the base 3 and are positioned at base 3 the same side, first light source 1 is made up of multiple LED chips being sequentially connected in series and being looped around secondary light source 2 periphery, secondary light source 2 also can be made up of the LED chip of multiple serial or parallel connections, and the brightness of the first light source 1 is more than secondary light source 2.
First diffuser 4 and the second diffuser 5 are respectively mounted on the base 3, and the first diffuser 4 is located on the first light source 1 and secondary light source 2, and the second diffuser 5 is located at the first diffuser 4 periphery. The ray refractive index of the second diffuser 5 is more than the ray refractive index of the first diffuser 4. When first light source 1 or secondary light source 2 are lighted, by there is scattering after the first diffuser 4 refraction in light, light after scattering is by scattering again after the second diffuser 5 refraction, so, the setting of the first diffuser 4 and the second diffuser 5, be conducive to improving the diversity of light, improve the uniformity of light intensity.
Supply module and switching circuit are respectively mounted on the base 3, and switching circuit connects supply module, the first light source 1 and secondary light source 2 respectively, and are used for controlling supply module and power to the first light source 1 or secondary light source 2.
With reference to Fig. 3, in present embodiment, switching circuit includes audion Q1, the first resistance R1, the second resistance R2 and the three resistance R3. Audion Q1 base stage is connected to supply module ground connection after the first light source 1 of connecting by the first resistance R1; Ground connection after audion Q1 emitter stage series connection secondary light source 2; Audion Q1 colelctor electrode connects supply module by the second resistance R2, and by the 3rd resistance R3 ground connection. Additionally, the outfan of supply module is in series with switch J1, switch J1 connects the first resistance R1 and the second resistance R2 respectively away from one end of supply module. So, after switch J1 closes, supply module normal power supply, when the first light source 1 normal operation, audion Q1 base voltage is in low level, and audion Q1 ends, and secondary light source 2 does not work; When the first light source 1 open circuit, audion Q1 base voltage is high level, and audion Q1 turns on, and secondary light source 2 works. Therefore, the setting of switching circuit, can when the first light source 1 exception, automatic switchover secondary light source 2 replaces the first light source 1 and works, so that this LED is properly functioning. And, owing to the first light source 1 brightness is more than secondary light source 2, after secondary light source 2 work, from brightness, user can determine whether out that the first light source 1 is abnormal, thus on-call maintenance.
In present embodiment, supply module can adopt alternating current power supply, DC source or battery.
In present embodiment, base 3 is provided with multiple fin 6, fin 6 side inserted base 3 away from the side of the first light source 1 and secondary light source 2, and opposite side highlights base 3, and fin 6 is arranged in parallel, and the spacing between two fin 6 of arbitrary neighborhood is equal. The setting of fin 6 so that the heat assembled on base 3 quickly scatters and disappears, thus the reliability of this pair of light source led lamp work can be ensured, increases the service life.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
